I'll let him tell you in his words. We're all familiar with Giacomo from Vance's novel; it would be GREAT to read about the real person!
Arba Sicula is a non-profit International Organization that promotes the Language and Culture of Sicily. It is part of The Modern Language Department at St. John's University in New York. They produce a bi-annual news letter, Sicilia Parra (Sicily Speaks) and have accepted for publication an article I have written on the 17th century sculptor, Giacomo Serpotta. It should be in print fairly soon.
